Hello Rajesh, 

As your form was accepted and no error was found on return most propbably it won't cause you a lot of trouble. You might get your hall ticket but as we cannot risk the application orelse it would cost you the attemption of examination I would rather suggest you to kindly contact the authorities incharged and involved with examination. Please approach them as soon as possible through mail or phone. They would guide you the further process as to which either you have to fil another form they might givw youa solution for the error. Do not worry.
All the Best!
